چکیده
With the assumption that the X(1835) and η(1760) recently observed by the BES Collaboration are the 3 1 S 0 meson states, the strong decays of these two states are investigated in the 3 P 0 decay model. We find that the predicted total widths of the X(1835) and η(1760) can be reasonably reproduced with the X(18350) − η(1760) mixing angle lying on the range q ¯ q members seems reasonable.

In the framework of the 3 P 0 meson decay model, the strong decays of the 3 1 S 0 and 4 1 S 0 s¯ s states are investigated. It is found that in the presence of the initial state mass being 2.24 GeV, the total widths of the 3 1 S 0 and 4 1 S 0 s¯ s states are about 438 MeV and 125 MeV, respectively. Also, when the initial state mass varies from 2220 to 2400 MeV, the total width of the 4 1 S 0 s¯...
